If they shut off your power, give them notice in writing as soon as you can. Landlords in WA can never shut off power (except briefly to make repairs) and a tenancy without water is not a tenancy. They would be making a terrible error if they shut off your power. If that happens, give them notice in writing to knock it off, and get the power turned back on. E Powell

Thank you so much Elizabeth! I really appreciate the resources you have provided me. We do have leases, but our landlord has not provided them to the new owners as far as we know. I will keep trying to get her to send them over. There are 9 other people being affected by this, so I really appreciate the help. Thanks again!

If its the old landlord shutting the power off then really your only solution is to get it turned on in your name. You cannot force him to keep it in his name if he doesnt even own the residence anymore and you cannot force the new owners to put it in their name.
